Objective; To evaluate the reliability and reasonability of maxillofacial skin color match using the digital camera. Methods; The stability of the experimental light source was evaluated before establishing the color measurement. 122 volunteers aged from 22 to 32 years were recorded by a Canon EOS 20D digital camera in studio environment when the light source was stable. Photographs were taken under a set exposure parameters(f/4.5,1/25 s,custom white balance,ISO 800) and saved as JPEG format. The CIE L~* a~* b~* color values were obtained from the digital images using Adobe Photoshop7.0 after color correction. All data were analyzed using SPSS 10. 0. Results;The experimental light source was stable in 21 to 70 minutes. It was suitable for color measurement during this period. The color parameters of all tested maxillofacial skin were:L~*49～66,a~*7 - 18,b~*5 -22. Conclusion;The assessment of maxillofacial skin color depend on method of measurement and instrument. The method of maxillofacial skin color matching by digital camera seems reliable.

Corticotropin-releasing factor(CRF)is one neuroendocrine peptide which is closely related with the stress.It has been proved that any stress can lead to the person and animal's blood CRF level increasing,and high-level CRF urges the hypothalamic neuron calcium ion inflow.Newborn pediatricians pay more attention to whether blood CRF level can act as one director of assessing severity of newborn hypoxic-schemic brain damage.This article reviews the CRF and it's acceptors,CRF secretion,CRF physiological action and it's adjustment,and hypoxia-ischemia stress and CRF,in order to provide the theory basis for reviewing the severity of hypoxic-schemic brain damage in neonates.

BACKGROUND: The meniscus has limited ability in repairing itself after being injured. However, tissue engineering provides a new way to meniscus repair after injury. Bone marrow mesenchymal stem cells (BMSCs), which possess the potential of multi-directional differentiations, can be ideal seed cells in meniscus tissue engineering. OBJECTIVE: To investigate the feasibility of differentiation of in vitro cultured porcine BMSCs into fibrochondrocyte phenotypes in inductive medium. METHODS: BMSCs were isolated with whole bone marrow culture method. Then, BMSCs of the third passage were digested and incubated in a medium containing transforming growth factor-β1, insulin-like growth factor-Ⅰ, dexamethasone and ascorbic acid in a 24-well plate at a density of 2.0×10~4/cm~2 in the experimental group. While in the control group, the DMEM-LG complete culture medium containing no inductive factor were used instead. At day 7, 14 and 21 after induction respectively, Toluidine blue staining and immunocytochemical staining were performed to detect differentiation. MAIN OUTCOME MEASURES: ①Population double time (PDT) of BMSCs; ②Morphological changes of BMSCs under light microscope;③Proteoglycan expression;④Collagen type Ⅰ and type Ⅱ expression. RESULTS AND CONCLUSION: ① The PDT of the second passage BMSCs was 2 days, which was the shortest. The PDT prolonged relatively after the fourth passage, which were 5 to 9 days. ② The BMSCs changed from a spindle-like appearance into a polygonal shape after induction. ③ In the experimental group, toluidine blue staining resulted in hyacinthine-stained cytoplasm and the blue was even deeper in the area where cells were dense; The degree of staining increased with the increasing induction time. While in the control group, only nucleus of BMSCs were stained blue. ④ Collagen type Ⅰ immunocytochemical staining was positive in both the experimental and the control group and there was no difference of significance between various induction time. No collagen type Ⅱwas seen expressed in the control group, while in the experimental group it was seen to be expressed steadily after 14 days of induction. It is indicated tlat BMSCs can be induced to synthesize fibrochondrocyte-characterized extracellular matrixes in vitro, which suggests that BMSCs are available as seed cells in meniscus tissue engineering.

BACKGROUND:Forceful fixation and enough blood supply in fracture site are the fundament for treating bone nonunion. OBJECTIVE:To investigate the outcome of autologous lilac bone-grafting and plate fixation in treatment of the ununited distal ulnar fracture with osseous defects. DESIGN,TIME AND SETTING:The own control study was performed at the Department of Orthopaedics,Sixth People's Hospital,Shanghai Jiao Tong University from August 2002 to May 2006. PARTICIPANTS:Of 21 cases of the ununited distal ulnar fracture with osseous defects,13 cases were induced by ulnar and radial fracture,and 8 cases were induced by ulnar fracture. There were 15 cases of open fracture and 6 cases of closed fracture of first onset. Bone defects were 1.5 cm-5.0 cm,averagely 3.1 cm. METHODS:Bone defects were filled with intercalary lilac grafts. Length and axial ray of ulna were controlled. Ulna was fixed utilizing 5-8 wells 1/3 tubular plate,reconstruction plate or locking compression plate. At least two screws were used at the distal end,and 3 or 4 screws were fixed in the proximal end,FoUow-up was conducted once per month to observe clinical appearances and radiograph in each patient. MAIN OUTCOME MEASURES:Fracture nonunion,dorsal extension and palmer flexion of wrist joint,pronation and supination of the forearm were measured. RESULTS:All 21 cases were followed up for a mean time of 14.7 months. All the patients obtained bony union,and a mean time of 4.6 months (ranged 3 to 7 months). The distal ulnar healed with < 10° of angular deformity in a coronal plane in one patient and with 15° of angulation in a sagittal plane in another one,while others (19 patients) obtained satisfactory alignment. The excellent and good rate was 90.5％. CONCLUSION:Intercalary bone-grafting with autologous lilac and secure fixation for treating the ununited distal ulnar fracture with osseous defects can reconstruct ulnar length,correct deformities,and obtain good bone healing and functional recovery.

OBJECTIVE:To provide reference for clinical rational drug use. METHODS:The drug sales amount,DDDs, DDC and major pharmaceutical enterprises in 273 sample hospitals of Yangtze River basin in 2014 were statistically analyzed. RE-SULTS:The growth of consumption sum slowed down gradually. The anti-infective drugs,cardiovascular drugs and nervous sys-tem drugs occupied the medical mainstream market. Top 3 drugs in the list of consumption sum in consecutive 4 quarters were monosialotetrahexosylganglioside,thymic peptide and lansoprazole. Nearly half of top 15 drugs were auxiliary drugs;Chinese pat-ent medicines grew increasingly and appeared in the list. The sales enterprises were mainly domestic enterprises,which concentrat-ed in Sichuan,Chongqing,Jiangsu province,and other places. CONCLUSIONS:The structure of drug use in sample hospitals is basically consistent with the spectrum of disease in China. However,there is deviation between auxiliary drug use and international guide,and the rationality of clinical drug use needs to be improved.

Objective To investigate the clinical significance of peripheral blood parameters including immature reticulocyte fraction (IRF) in monitoring the hematopoietic recovery of patients with acute myeloid leukemia aftcr receiving consolidation chemotherapy with high dose cytarabine (HDAC).Methods The peripheral blood parameters,including absolute neutrophil (ANC) and platelet (Plt) counts as well as IRF,were measured by Sysmex XE-2100 automated hematology analyzer before and after consolidation chemotherapy with HDAC in 30 patients with acute myeloid leukemia.These peripheral blood parameters were further statistically analyzed and compared.Results Following consolidation chemotherapy,the median time to recovery for ANC,Plt and IRF was (9.2±2.5) days,(11.3±3.7) days and (5.0±2.6) days,respectively.In comparison with ANC and Plt recovery,IRF showed significantly early recovery (P ＜ 0.05).Additionally,ANC raised preceding Plt recovery (P ＜ 0.05).However,the median recovery time of ANC,Plt and IRF showed little difference among these patients further subgrouped according to FAB and risk based classification (P ＞ 0.05).Conclusion IRF is an early indicator for the hematopoietic recovery of patients with acute myeloid leukemia following consolidation chemotherapy with HDAC,which could provide important clinical information to evaluate therapeutic efficacy.
